How many IVF operations do IVF babies need?
IVF is an assisted reproductive technology that helps couples who cannot conceive naturally realize their reproductive dreams. This technology involves multiple steps and processes, and the actual number of IVF operations varies depending on the individual situation of the couple.
1. Test tube baby preparation
Before IVF surgery, couples need to undergo a series of physical examinations to determine whether it is suitable for IVF. These tests may include ovarian function tests and endometrial assessment in women, as well as sperm quality tests in men.
If the test results are normal, the next step is to prepare for assisted reproductive technology. This includes women injecting ovulation guidance drugs to stimulate ovarian development, and monitoring the growth of follicles. At the same time, men need to provide semen samples for laboratory treatment.
In the early stage of preparation, IVF surgery is usually not required. However, if other health problems are found, such as fallopian tube obstruction or male sperm dysfunction, surgical intervention may be required.
2. Egg taking and sperm treatment
Once the female ovary develops well and produces enough mature eggs, the next step of IVF surgery is to take out the eggs and sperm provided by men for laboratory treatment.
Usually, doctors will use ultrasound guided invasive technology to puncture the eggs. Then, the egg will be fertilized with sperm in vitro, or a single sperm will be directly injected into the egg to increase the chance of pregnancy.
Sperm processing may include semen quality assessment, sperm washing and screening to improve fertilization opportunities.
3. Embryo culture and embryo transfer
After in vitro fertilization, the fertilized eggs will be placed in a culture dish for embryo culture. The culture time is usually 5-6 days, so that the embryo can develop to a higher quality level.
At the same time, doctors and couples need to discuss the number of embryo transfers. Depending on your personal circumstances and your doctor's advice, you may choose to transfer one or more embryos back into your mother's womb. In the process of culture, the quality and quantity of embryos will affect whether multiple attempts are needed.
Embryo transfer is generally a painless and non-invasive process. Doctors will introduce the screened embryos into the uterine cavity with thin tubes to maximize the implantation rate.
4. Multiple attempts and success rate
The success rate of IVF surgery varies with many factors, including age, childbearing history, and illness. According to clinical research, female age is an important factor affecting the success rate.
If the first IVF operation fails to achieve pregnancy, the couple can choose to try again. After comprehensive assessment and under the guidance of doctors, plans for the next attempt can be made and appropriate measures can be taken to improve the success rate.
It should be noted that every IVF operation has certain pressure on couples economically, physically and psychologically. Therefore, couples should fully communicate with doctors and consider other options before discussing trying again.
Summary
IVF surgery is a complex and individualized process, which needs to be determined according to the specific situation of the couple whether to try many times. In the preparation stage, egg taking and sperm treatment, embryo culture and embryo transfer are the key steps of the whole process. The success rate is affected by many factors, including age, childbearing history and illness. Couples need to fully communicate with doctors and consider multiple factors to decide whether to try IVF surgery again.
